Insulation Company in Carrollton, TX
Woolsey Attic Insulation is the insulation company Carrollton homeowners call when their attic stops doing its job. Most homes here were built between 1970 and 2000, and most still have the original fiberglass batts that were installed decades ago. Texas heat doesn’t just make those batts uncomfortable. It settles them, compresses them, and bakes the R-value right out of them. When attic temperatures climb past 140°F in a Carrollton July, a poorly insulated attic pushes that heat straight down into your living room. That’s the problem we fix. Call (469) 916-4622 and you’ll get a real person, a straight answer, and a written price before any work starts.
Why Carrollton Homes Are Different
Carrollton’s housing stock is dominated by 1970s through 1990s suburban tract homes. That’s not a knock on the homes. It’s a fact about how they were insulated. Builders in that era typically installed R-19 fiberglass batts in the attic, sometimes R-11 or R-13 in exterior walls, and called it a day. Thirty or forty years of North Texas humidity later, those batts have settled, shifted, and in many cases been chewed through by rodents or soaked by a roof leak. The result is an attic that tests at R-19 on paper but performs closer to R-9 in practice.
The Castle Hills neighborhood has its own specific pattern. Many homes there were built with radiant barrier roof decking, which is a good idea on paper. But we regularly find radiant barrier that was never installed in sections, or stapled incorrectly so it sags away from the roof sheathing. That creates uneven attic temperatures: one bedroom stays comfortable while the room over the garage bakes. It’s a fixable problem, but it doesn’t show up on a standard inspection.
Carrollton also gets the full Dallas-Fort Worth climate swing. Summers bring months of 95°F days with humidity that makes the air feel like soup. Winters bring the occasional hard freeze that sends homeowners scrambling. Both extremes hit the attic first, and both punish under-insulated homes the hardest.
Our Main Carrollton Services
Most Carrollton homeowners call us about one of two things: bringing an old attic up to modern standards, or sealing the home with spray foam. Here’s what each one looks like in Carrollton.
Attic Insulation in Carrollton
Attic insulation in Carrollton usually means removing old, settled fiberglass batts and replacing them with blown-in cellulose or fiberglass to R-38 to R-60. That’s the level the Department of Energy recommends for this climate zone, and it makes an immediate difference in a home where the original R-19 batts have given up. We also air seal the attic floor before blowing in new material, because insulation without air sealing just filters hot air through the gaps. Learn more about Attic Insulation in Carrollton.

Spray Foam Insulation in Carrollton
Spray foam is a two-part liquid that expands on contact and seals every gap, crack, and seam in the attic. In Carrollton’s 1970s and 1980s homes, where original batts sag between the joists and leave the top plates exposed, spray foam brings the attic into the conditioned envelope of the house. That means the attic temperature stays within a few degrees of the living space, which cuts cooling load in summer and prevents condensation in winter. See our Spray Foam Insulation in Carrollton page for details.
